Latest Patents
Qiuhua Zhang holds two notable patents. The first patent, titled "Method for synthesizing silicoaluminophosphate-34 molecular sieves using monoisopropanolamine," describes a procedure for creating small crystals of silicoaluminophosphate-34 (SAPO-34) molecular sieves characterized by high structural purity. This method involves initially forming a slurry composed of monoisopropanolamine, which is then aged to create an aged slurry. The crystallization of silicoaluminophosphate molecular sieves is subsequently induced from this aged slurry.
The second patent, titled "Method for synthesizing silicoaluminophosphate-34 molecular sieves," also focuses on the synthesis of SAPO-34 molecular sieves. This method details the formation of two separate slurries: the first slurry contains sources of phosphorus, aluminum, and silicon, along with an organic structure directing agent, while the second slurry has similar components. Both slurries are aged separately before being combined to induce crystallization of the SAPO-34 molecular sieves.
